After a certain period of time in the operating room, there will be varying degrees of contamination, in addition to routine maintenance, but also in accordance with the relevant provisions of the regular monitoring, in order to ensure that the cleanliness of the operating room is qualified, so as to ensure that the preparation of the preparation is qualified.
Preparation of the operating room; the minimum number of sampling points and the location of the determination; suspended particles number test; settled bacteria number test; sampling methods; culture; colony counting BCJ-1D laser dust particle counter comprehensive indicators in line with national standards (GB6167.I-85 ), the minimum test particle size of 0.3 O,m, the air sampling volume of 2.83L/min instrument self-purification with a total count of 0.3 O,m file continuously. ,m file total count for three consecutive times (1min / times) for zero time required less than 10 min, can be counted on any channel for real-time observation of the operating room internal pollution sources are mainly people, goods, equipment, etc. People are the largest source of pollution, accounting for about 90% of the filtration method with its capture rate is high, but also the economy and is widely used in the air particles or most of the particles can be filtered out Therefore, the normal operating room is Therefore, the normal operating room is almost sterile or meet the standard, more laser dust particle counter for monitoring and control of high-efficiency air filter replacement cycle is generally 1-2 years, the primary filter replacement cycle should be shorter and the replacement cycle of high-efficiency air filters is not fixed, should be based on the use of the environment of the air quality, the use of the frequency and duration of time, monitoring the results of the results of close to the standard test when the replacement of the good, both To ensure that the cleanliness of the operating room qualified, but also to avoid unnecessary waste
The clean operating room using purified air system after thorough filtration, the use of natural sedimentation method of sampling and cultivation, are in line with the requirements of a class of air purification for the operation to provide a safe and secure. After purification of the clean operating room, can only do to reduce or eliminate bacteria in the air, can not play on the surface of the clothing and adsorption of dust sterilization effect. Therefore, strict management of clean operating room hygiene, the implementation of air purification, regular care, the maintenance of clean indoor areas, control of sources of contamination as well as reduce the phenomenon of bacterial infection is particularly critical.
In short, the management of clean operating room is crucial, effective, scientific, strict management to ensure the quality of medical care, infection control plays a key role.
